Log Message:
py-pspdfutils: update to 3.1.1.

3.1.1

This release is a minor update that requires pypdf 3.15.2, as this
release changed some test results cosmetically.

There is no need to upgrade if you’re not concerned with running
the tests.

3.1.0

This release adds the ability to pass the page specs to psnup
without the --specs flag, for backwards compatibility with PSUtils
1.x. This usage is deprecated, and is not recommended, but in 1.x
it was mandatory.

The release also fixes PDF output when the output is sent to standard
output.

Thanks to James Clark for reporting both bugs.

3.0.9

This release updates to PyPDF 3.15.
